Testing Automotive Interior Materials with a Universal Testing System

Andrew DeWolfe — Fri, 24 Feb 2012 16:33:00 GMT

I’ve had a few car breakdowns in my life that have left me stranded on the highway. Whenever this happens, I envy the lucky people who manage to live life without the need to own or drive an automobile on a daily basis. The trouble is that there is no way I can do all that I want to do in the time I have available without having my own car. Besides, my hatred of my vehicle quickly passes when I think about how reliable my car actually is. When you think about that there are roughly 30,000 individual parts in a modern automobile and with all the abuses we subject all these parts to – potholes, temperature extremes, lack of maintenance – it’s truly amazing that problems arise as seldom as they do. That’s because an incredible amount of R&D effort and testing goes into making sure all of these parts are properly engineered into the system.

Pipette Tips: Determining Stiffness with a Bend Test

Debbi Cohen — Thu, 02 Feb 2012 16:29:00 GMT

Pipette Tip Bend Test

A pipette (also spelled pipet or pipettor) is used to aspirate and dispense fluids in wells for analysis and further testing. There are many types of piston pipettes, but all work on essentially the same principle; hand or mechanical pressure on a piston or plunger working over a fixed length in a cylinder forces a pre-determined volume of liquid out of the orifice of the pipette. Pipettes are used to hold body fluids, oily fluids, concentrated acids, nucleic acids, and volatile compounds.

Performing an ASTM D3167 Adhesive Floating Roller Peel Test

Andrew DeWolfe — Mon, 29 Aug 2011 18:20:00 GMT

The floating roller peel test is one of many types of tests designed to measure the average peel force of an adhesive or other bonding agent. The other common peel tests are the 90 degree, 180 degree, and T-Peel. Although not suitable for every application, the floating roller is a very accurate and easy method to obtain average peel force values.

Dental Material Tensile Adhesion and Bond Shear Strength ISO11405

Debbi Cohen — Wed, 01 Jun 2011 15:43:00 GMT

Dental composite resins are types of synthetic resins which are used in dentistry as restorative material or adhesives. Synthetic resins evolved as restorative materials since they were insoluble, aesthetic, insensitive to dehydration, easy to manipulate and reasonably inexpensive. Many dentists today use resin fillings instead of amalgam fillings. Composite resins are also used for reshaping teeth, partial crowns, and to adhere retainers.

Micro EP Used for Micro Tensile Testing of Plant Fibers

Nicholas Schaulsohn — Fri, 25 Mar 2011 14:47:00 GMT

We recently worked with a leading research university that needed a system to test the tensile properties of plant fibers. Scientists at the university required a system that was capable of holding small wood fibers and testing them at extremely low forces. The testing system also needed to be compatible with a video microscope and had to be able to perform tests inside a liquid bath.

Egg Compression Strength Test

Nicholas Schaulsohn — Mon, 28 Feb 2011 22:05:00 GMT

We’ve all attempted to break an egg by squeezing it with our hands and failed miserably. Like an arch under a bridge, the shape of an egg helps distribute the applied force across the entire surface. Cracking an egg with the edge of a pan is easy because the force is concentrated on one small section of shell. When force is applied more evenly eggs appear to be much stronger.

Alaska Department of Fish and Game Tests Twine for Crab Pots Using ADMET eXpert System

Nicholas Schaulsohn — Tue, 30 Nov 2010 21:47:00 GMT

The Alaska Department of Fish and Game (ADF&G) has broad responsibilities including oversight of the crab fisheries in Alaskan waters. A consequence of the pot gear used by the industry is a phenomenon called “ghost fishing,” which happens when functional pots are lost but continue to trap and kill crabs and other organisms. In response, regulations were enacted that require one sidewall of all crab pots have an opening that is secured with a biodegradable 100% cotton twine that would break down over time, fail and allow the trapped organisms to escape.

University of Michigan Researchers Use ADMET to Test Mechanical Properties of Bone

Nicholas Schaulsohn — Tue, 30 Nov 2010 20:56:00 GMT

A University of Michigan research laboratory is conducting mechanical testing of bone to measure its mechanical properties. Led by Prof. David Kohn, the lab conducts destructive tests that flex the bone to failure in a four-point bend fixture. Their research calls for a system that can accurately control the deflection rate, and generate a flexural stress versus strain curve. Another test results in a cyclic control profile in which the specimen is cycled between two defined values at a frequency of one Hertz for two hours.
